Exploring the Impact of AI-Assisted Speaking Practice on EFL Learners' Speaking Proficiency and Motivation: A Mixed-Method Study

Abstract

Existing studies have shown that Artificial Intelligence (AI) tools can effectively improve speaking proficiency, including aspects such as pronunciation, fluency, grammar and vocabulary. Meanwhile, some research has demonstrated their potential in fostering learner motivation and interest. However, current research lacks investigating both these tools' effectiveness in boosting speaking skills and enhancing psychological factors like motivation and anxiety reduction. Building on the gap, this study investigates the impact of AI-assisted speaking applications on enhancing English as a Foreign Language (EFL) speaking skills and students’ intrinsic motivation for speaking practice. The research involved 70 sophomore English major students at a university in China, with the experimental class using the AI app EAP Talk for speaking practice over a four-week period, while the control class followed traditional speaking practice methods without AI support. A mixed-methods approach was adopted in this study, including pre- and post-tests via a speech assessment platform, a survey, and semi-structured interviews to examine improvements in speaking proficiency alongside intrinsic motivation. The findings from the pre- and post-tests reveal significant improvements in the experimental class’s speaking skills, particularly in pronunciation and fluency. Survey results revealed that most students found AI app helpful in increasing their motivation in speaking practice and boosting confidence in learning English. Many reported improved speaking skills and expressed willingness to continue using AI tool. Interview data further indicated that students perceived AI as an effective tool in reducing their speaking anxiety, while also appreciating the flexibility to practice anytime and anywhere. This study offers insights into the application of AI tools in EFL education, highlighting their potential to enhance both speaking proficiency and learner motivation.
